semver 0.40.0

=============



[![PGXN version](https://badge.fury.io/pg/semver.svg)](https://badge.fury.io/pg/semver)

[![Build Status](https://github.com/theory/pg-semver/workflows/CI/badge.svg)](https://github.com/theory/pg-semver/actions)



This library contains a single PostgreSQL extension, a data type called

"semver". It's an implementation of the version number format specified by the

[Semantic Versioning 2.0.0 Specification](https://semver.org/spec/v2.0.0.html).



Installation

------------



To build semver:



    make

    make install

    make installcheck



If you encounter an error such as:



    "Makefile", line 8: Need an operator



You need to use GNU make, which may well be installed on your system as

`gmake`:



    gmake

    gmake install

    gmake installcheck



If you encounter an error such as:



    make: pg_config: Command not found



Be sure that you have `pg_config` installed and in your path. If you used a

package management system such as RPM to install PostgreSQL, be sure that the

`-devel` package is also installed. If necessary tell the build process where

to find it:



    env PG_CONFIG=/path/to/pg_config make && make installcheck && make install



If you encounter an error such as:



    ERROR:  must be owner of database regression



You need to run the test suite using a super user, such as the default

"postgres" super user:



    make installcheck PGUSER=postgres



Once semver is installed, you can add it to a database. If you're running

PostgreSQL 9.1.0 or greater, it's a simple as connecting to a database as a

super user and running:



    CREATE EXTENSION semver;



If you've upgraded your cluster to PostgreSQL 9.1 and already had semver

installed, you can upgrade it to a properly packaged extension with:



    CREATE EXTENSION semver FROM unpackaged;



For versions of PostgreSQL less than 9.1.0, you'll need to run the

installation script:



    psql -d mydb -f /path/to/pgsql/share/contrib/semver.sql



If you want to install semver and all of its supporting objects into a

specific schema, use the `PGOPTIONS` environment variable to specify the

schema, like so:



    PGOPTIONS=--search_path=extensions psql -d mydb -f semver.sql



Dependencies

------------

The `semver` data type has no dependencies other than PostgreSQL and,

for testing, PL/pgSQL.
